Hi! I may have a tip for you. OLEDs emit at very specific wavelengths due to materials being used and there are very few materials that make for majority of displays. If you can create lenses that would selectively block very specific wavelengths (probably using same chemicals) then OLED displays would be dark or greatly attenuated and everything else that emits diffuse light would be only slightly attenuated (only small part of the continuous spectrum would be blocked at the specific wavelength).
